Not sure if this reaches 20,000 lumens, but nevertheless the beam is very bright. I nearly dazzled myself in daylight with reflection off a gloss surface in the house, and it easily outshines any other torch i have and a 100W incandescent light.Build quality is excellent, only slight gripe being the plastic cover on the USB charge point. As other have said it's not small (over 1 ft long) so no good in confined spaces, but if you want a bright torch for outdoors and don't mind it not fitting in a pocket, this is just the ticket.

Thought it was brilliant, but the only problem is it won’t charge, which is disappointing because it was very useful!

Worked for a few weeks, and now is pretty much dead. On/off button is unresponsive.Wasn't that bright when it worked either.Save yourself some money and avoid it.

This product is a good weight but worth the brightness. You can have it wide or pinpoint this light lights up all my garden I would recommend not looking at the brightness. It’s too bright I would recommend this product to everyone who needs a very bright light

Bought for my husband he loved it vety handy for walking the dog at night very bright and the fladh function is good

A very powerful torch with an extremely bright beam.I was initially delighted with this torch, but this experience quickly soured as a discovered that the battery life is very short. I guess that is to be expected to a degree, given the brightness.The main issue is that after about one month of semi-regular usage, it had completely stopped working. It appears to take a charge, but it will no longer switch on.It also took near one month to arrive by post.I really would not recommend this product.

It does very good what it is said!

Bought two of these now and very impressed. Battery life seems good and lasts a good few weeks between charges. Charge it up before it fully discharges so can’t say exactly. I like that the rechargeable batteries can be changed and aren’t built in. Minor grumble would be at max range as in the most narrow beam you get a cross in the beam that is slightly irritating. Knocked a star off as the first one bought kept switching off but a quick stretch of the spring holding the batteries cured this. Just about to buy a third for an admiring neighbour. Just hope it’s as good as the first two?
